Today in history - 1876

Drinking at a saloon in Deadwood, Dakota Territory, Jack McCall notices Wild Bill Hickok playing poker at a corner table. Then he calmly walks over to the table and shoots Hickok in the back of the head with a .45 revolver. The professional gambler and onetime lawman was holding a pair of Aces and a pair of eights, now known as the "Dead Man's Hand."
